    The present invention relates to a method for creating a sealing surface in the region of the ceiling and / or the side areas of a particular underground space, the application of the method in the preparation of a draining or pressurized water tunneling and a drainage or pressurized water tunneling made using the method according to the preambles of the independent claims.
    The task of creating sealing surfaces against water penetration in the area of the ceiling and the side areas, turns in particular in underground vaults and tunnels, which serve transport or storage purposes. In such uses, the interior should be kept as free as possible from the environment zufliessendem water.
    For the preparation of such sealing surfaces in the ceiling and wall area of tunnels today various methods are known, wherein in most processes a sealing membrane in the area of the ceiling and the side areas is arranged, which is accomplished in different ways.
    Thus, it is known to attach a geomembrane with anchoring elements in the surrounding the tunnel arch rock and subsequently seal the passage points of the anchoring elements by the geomembrane. This process is labor intensive and has the significant disadvantage that the geomembrane is injured with the anchoring elements and the subsequently re-sealed sites pose potential problem areas.
    Further, it is known to fasten plate-like fasteners made of a thermoplastic material by means of anchoring elements in the rock surrounding the tunnel vault and then to attach a thermoplastic geomembrane by welding to these fasteners. This method is also labor intensive and has the disadvantage that the geomembrane is structurally changed in the region of their welds with the fasteners, whereby these attachment points also pose potential problem areas.
    It is also known to attach a geomembrane by means of hot melt adhesive on the boundaries of the tunnel vault. However, this method is only suitable for uniform, clean and dry boundary surfaces and is therefore practically possible only in tunnels made of tubbing elements.
    It is therefore the task of providing solutions that do not have the disadvantages of the prior art mentioned above or at least partially avoided.
    This object is achieved by the method for creating a sealing surface in the area of the ceiling and / or the side areas of a particular underground space, in particular a tunnel, according to claim 1.
    According to this method, which is the first aspect of the invention, a waterproof sealing sheet is connected via a foam-like adhesive material directly or indirectly with the boundaries of the space in the ceiling and / or the side areas, in such a way that the geomembrane over the foamy adhesive material is carried by the confines of the room. This means that the weight forces of the geomembrane are conducted via one or more zones formed by the foam-like adhesive material to the boundaries of the space.
    "Directly connected" means that between the boundaries of the space and the geomembrane only the foam-like adhesive material is used to connect the geomembrane to the boundaries of the room.
    "Indirectly connected" means that the geomembrane is connected to a body disposed between the boundaries of the space and the geomembrane, which in turn is directly or indirectly, i. E. beyond other physicalities, is connected to the boundaries of the space, wherein the connection between the geomembrane and the physicality and / or the connection between the physicality and the boundaries of the space is formed by the foam-like adhesive material. Thus, e.g. the geomembrane on its wet side be laminated with a drainage fleece, which is then connected by means of the foam-like adhesive material with the boundaries of the room. Also, it is e.g. conceivable that a drainage mat is arranged between the geomembrane and the boundaries of the space, which is mechanically or by means of a foam-like adhesive material connected to the boundaries of the room and with which the geomembrane is connected by means of a foam-like adhesive material.
    The inventive method, it is possible to create a high-quality waterproof seal in the area of the ceiling and the side walls of a room in a harsh and especially wet site conditions in a simple and cost-effective manner.
    Preferably, the geomembrane is arranged with its intended as a wet side outer surface opposite to the boundaries of the space in the ceiling and / or the side areas and then the foam-like adhesive material in the uncured or non-hardened state in the area between the geomembrane and the boundaries of the space introduced, preferably by this is applied to the intended as the wet side outer surface of the geomembrane. In the course of or subsequent to this, one or more connections are made between the geomembrane and the boundaries of the space via the non-cured or non-set foam-like adhesive material arranged therebetween. In this condition, the foam-like adhesive material is then cured, thereby being able to transfer the weight forces of the sealing sheet to the boundaries of the space. Such an approach has proven to be particularly practical.
    It is advantageous that the geomembrane is moved before hardening or setting of the foam-like adhesive material in the direction of the boundaries of the room and / or pressed against the boundaries of the room, for the production and / or intensification of the Connection or the connections between the geomembrane and the boundaries of the space over the adhesive material. This makes it possible to reduce the required amount of foam-like adhesive material and thus save costs.
    Preferably, the introduction of the foam-like adhesive material is completed before the sealing sheet is moved in the direction of the boundaries of the room and / or pressed against the boundaries of the room, so that simple, manageable steps result and the safety is increased.
    It is in a first preferred variant in inventive method in which the sealing web is moved before curing or setting of the foam-like adhesive material in the direction of the boundaries of the room and / or pressed against the boundaries of the room, the Geomembrane in all areas in which via the adhesive material, a compound thereof is made with the boundaries of the space, moved substantially simultaneously to the boundaries of the room and / or pressed against the boundaries of the room. This first variant is particularly suitable for methods in which the geomembrane is connected exclusively in the area of the ceiling with the boundaries of the room.
    In a second preferred variant, in the aforementioned method, in the event that the geomembrane is connected in the region of the ceiling and in the region of the side regions of the room on the foam-like adhesive material with its limitations, the geomembrane first in the region of Ceiling towards the boundaries of the room moved and / or pushed against the boundaries of the room and then moved in the area of the side areas towards the boundaries of the room and / or pressed against the boundaries of the room. In this way, in particular in the event that the sealing web is pressed against the boundaries of the room, it can be ensured that a sufficiently long sealing web section is present in the ceiling region in order to allow it to be pressed against the boundaries.
    Advantageously, the geomembrane is moved by inflating one or more airbags to the boundaries of the room and / or pressed against the boundaries of the room. This procedure has the advantage that no complicated mechanical devices are required for this purpose and in a simple and cost-effective manner, large strokes and uniform pressure forces can be realized. Another great advantage of using the air cushion is that they adapt to any contours and take up little space in the non-inflated state.
    In a further preferred embodiment of the inventive method, a drainage mat or drainage path is arranged between the boundaries of the space and the geomembrane in the region of the ceiling and / or the side regions of the room, which via the foam-like adhesive material both with the limitations of the room also connected to the geomembrane. This embodiment is particularly advantageous if a drainage gap is to be made available on the outside of the sealing surface and cost-effective, commercially available semifinished materials (sealing membrane, drainage mat or drainage membrane) are to be used.
    It is preferred in a first sub-variant that the foam-like adhesive material is introduced both in the area between the geomembrane and the drainage mat or drainage path as well as in the area between the drainage mat or drainage path and the boundaries of the room, preferably in each case in identical places. This first sub-variant is particularly suitable for processes in which drainage mats or drainage membranes are used, which are not or only poorly penetrated by the foam-like adhesive material.
    In a second preferred sub-variant, the foam-like adhesive material is introduced either in the region between the geomembrane and the drainage mat or drainage membrane or in the region between the drainage mat or drainage membrane and the boundaries of the room. This second sub-variant is suitable for processes in which drainage mats or drainage membranes are used, which are readily penetrated by the foam-like adhesive material, in particular when the sealing membrane is pressed against the boundaries of the room after the introduction of the foam-like adhesive material. It has the advantage that it is less labor-intensive than the first sub-variant.
    In yet another preferred embodiment of the inventive method, the foam-like adhesive material is introduced in the form of individual adhesive material points and / or individual adhesive bead, so that the sealing sheet after curing or setting of the foam-like adhesive material only selectively and / or linearly over the adhesive material is connected to the boundaries of the room, in such a way that in the area of the ceiling any leaking from the boundaries of the room and reaching the surface of the geomembrane water can flow on the geomembrane over the side areas.
    The arrangement of the geomembrane opposite the boundaries of the space in the area of the ceiling and / or the side areas, optionally with a drainage mat or drainage path thereon, advantageously takes place by means of a support structure, preferably in such a way that the geomembrane and optionally the drainage mat or drainage track arranged thereon follows or follows substantially the contour of the boundaries of the space in these areas. As a result, the arrangement of the geomembrane opposite to the boundaries of the space is greatly facilitated.
    The introduction of the foam-like adhesive material in the region between the geomembrane and the boundaries of the space is preferably carried out from a longitudinal side of the geomembrane ago or from both longitudinal sides of the geomembrane ago. Depending on the method and local conditions, one or the other alternative may be more advantageous.
    The geomembrane advantageously has a substantially uniform width, preferably a width of 2 m. Such geomembranes can be handled well in roll form.
    In yet another preferred embodiment of the method, a sealing surface is created in the region of the ceiling and / or the side regions of a tunnel from a plurality of geomembranes. In this case, the geomembranes are each connected in the tunnel circumferential direction so connected to the boundaries of the tunnel that in the tunnel longitudinal direction successive geomembrane overlap each other.
    It is preferred that the geomembranes are each waterproof connected to each other in the overlapping area, preferably by gluing or welding.
    In this way, can be made of several geomembranes large, continuous watertight sealing surfaces.
    As a foam-like adhesive material preferably a PU foam adhesive is used. Such foam adhesives are commercially available as single and multi-component foam adhesives, expand with good stability of the foam before curing to a multiple of their original volume and also have a tremendous adhesion to problematic and especially wet substrates.
    As a geomembrane is preferably a plastic sealing strip, preferably made of a thermoplastic material, more preferably from a polyolefin or PVC, used, preferably with a thickness less than or equal to 3 mm. Such geomembranes are commercially available in a wide variety, easy to process and also tested for a long time in the field of structural waterproofing.
    Also, it is preferred in some cases that in the inventive method, a geomembrane is used, which on its intended as a wet side outer surface with means for improving the connection with the foam-like adhesive and / or means for ensuring a drainage gap between the geomembrane and the boundaries of the space is provided, preferably with projecting elements, in particular of the geomembrane protruding bristles, rods, cones or nubs, or with a nonwoven. In this way, the adhesion of the geomembrane to the foam-like adhesive can be significantly improved or, depending on the adhesive material and geomembrane material, first produced and / or a drainage gap can be ensured even without the use of a drainage mat or a drainage fleece.
    Advantageously, the sealing web connected to the boundaries of the space is used after curing or setting of the foam-like adhesive material as a lost external formwork when concreting a building in the room, preferably when concreting an inner shell in the room.
    A second aspect of the invention relates to the application of the method according to the first aspect of the invention in the creation of a draining or pressurized water-retaining tunnel construction. In such applications, the benefits of the invention are particularly evident.
    A third aspect of the invention relates to a draining or pressurized water containing tunnel made using the method according to the first aspect of the invention.
    Further preferred embodiments of the invention will become apparent from the dependent claims and from the following description with reference to FIGS. 1 to 10.
    These figures show cross sections through a drained tunnel with concrete inner shell during different stages of construction in its preparation using the inventive method.
    After an underground cavity 2 has been generated in the rock 1 by explosive eruption, its limitations in the area of the ceiling and the sides for all-round protection with a layer of shotcrete 3 are coated. At the bottom of a concrete brine 4 is created. The shotcrete layer 3 and the concrete brines 4 now form the boundaries of the cavity 2. This situation is shown in FIG.
    Starting from the situation shown in Fig. 1 are then laid in the edge regions at the bottom of the cavity 2 in the longitudinal direction of the tunnel Drainageleitun gene 5, which serve after completion of the tunnel construction of the derivative of the mountain water. The Drainageleitun gene 5 here consist of polyethylene tubes, which are provided every 20 to 30 cm with radial holes. Furthermore, rails 7 are laid in the longitudinal direction of the tunnel in the edge regions of the tunneling column 4, on which a support structure 8 movable on rollers along the rails 7 is arranged, which has an outer contour which approximately corresponds to the clearance profile of the tunnel components to be created. On the boundary of the cavity 2 facing side of the outer contour of the support structure 8 distributed over the circumference a plurality of air-inflatable air cushion 6a, 6b, 6c, 6d, 6e are arranged. This situation is shown in FIG.
    In a next step, a 2 m wide sealing sheet 9 of a 3 mm thick PVC film, which is laminated on one side with a drainage fleece, arranged on the support structure 8, that their fleece-laminated outside the boundaries of the space 2 in Area of the ceiling and the side walls opposite, wherein it extends on both sides of the drainage lines 5 to the tunnel sole 4, to provide a length reserve, which ensures that the geomembrane 9 even after their intended installation in the lateral areas except for the tunnel sole 4 reaches down. This situation is shown in FIG.
    Starting from the situation shown in Fig. 3 is applied from both sides of the sealing sheet 9 pointwise PU foam 10 on the fleece-laminated outer side of the sealing sheet 9. This situation is shown in FIG.
    Then, in a next step, which is shown in Fig. 5, the uppermost arranged air cushion 6c inflated with compressed air, so that the sealing sheet 9 is pressed in the area of the ceiling substantially over the entire surface of the boundaries of the room 2.
    Subsequently, the arranged in the side areas air cushion 6a, 6b, 6d, 6e are inflated with compressed air, so that the sealing sheet 9 is pressed in the areas of the side walls substantially over the entire surface of the boundaries of the room 2. The situation after inflation of all the airbags is shown in FIG.
    In this case, in the areas where the PU foam on the fleece-laminated side of the sealing sheet 9 are arranged, made point connections between the geomembrane 9 and the boundaries of the space 2 via the disposed therebetween PU foam.
    After curing of the PU foam and the removal of the support structure 8 with the air cushion 6a, 6b, 6c, 6d, 6e, the sealing membrane is held over these punctual PU foam areas at the boundaries of the room 2. This situation is shown in FIG.
    In Tunnelvortriebsrichtung 9 further geomembrane 9 are installed in each case following the previously installed waterproofing membrane 9 by repeating each of the previously described with reference to FIGS. 2 to 7 steps. In each case, a zone is generated, in which overlap the lateral boundaries of each directly successive sealing webs 9. In this overlapping zone, the sealing sheets 9 are glued together watertight.
    After several geomembranes 9 are installed one behind the other in Tunnelvortriebsrichtung and joined together to form a coherent watertight sealing surface, an inner formwork 11 is placed with the outer contour of the future clearance profile of the tunnel to be created in the room 2 and a plurality of geomembranes 9 spanning section of the room 2 between the outer contour of this inner formwork 11 and the opposite sealing webs 9 formed space filled with concrete 12. These steps are shown in FIGS. 8 and 9. The geomembranes 9 serve as lost external formwork.
    After hardening of the concrete 12 and the removal of the inner formwork 11 of the tunneling is completed in this section in the shell, as shown in Fig. 10. The concrete 12 now forms a stable inner shell.
    The steps described above are repeated in tunneling direction, until the tunneling is created over its entire length in the shell.
    While preferred embodiments of the invention are described in the present application, it should be clearly understood that the invention is not limited to these and may be practiced otherwise within the scope of the following claims.
